    NEC requires at least one 20 amp laundry circuit in a dwelling unit and to consider it a 1500 VA load for the load calculations. One exception is multifamily dwellings with common laundry area on the premises.

    But if its just a dedicated closet with washer and dryer then we dont need to have a 1500VA laundry circuit?

    If you read what I wrote carefully, I think you will find that it says that what you describe requires the laundry circuit.

    Our younger daughter, who lives in England, has one of those. It was her only option, because it does not require a vent, and there is no way to run a vent pipe or duct from the laundry area to the outside. I think these take much longer to dry the clothes, and are therefore not energy efficient. Hers has a tank that she must empty at least once per dryer load.

    I would think the only true happy wives would be the ones that could afford to move into a house large enough to hold a couple of big front loaders.

    Our kids tell us that they are mandated because they are more energy efficient, but I'm not disagreeing with you; they are not technology people unless computers are considered.

    Both of our European missionary sons, one in England, one in Spain, have these and they are plumbed to drain so the tank doesn't need to be emptied; I'm told that some of their friends live where they do have to be emptied.

    It depends on what you are comparing it to. In terms of energy cost (money) it is probably more expensive than natural gas but less than electric heated dryer.
    In terms of carbon footprint it may be better than both. I have not seen that calculation.
    Since it is only removing the water and not heating and throwing away the air, it could be more efficient thermodynamically.

    Please note that I inserted a "preemptive I think" at the beginning of my sentence that mentioned energy efficiency. I have no facts to offer. My opinion was based solely on the amount of time I had to wait for the clothes to get dry, the last time I was at my daughter's house in England.

    Ventless condensing clothes dryers use domestic cold water to chill a cold plate to remove moisture from the dryer air. So figuring the environmental footprint is tricky due to the water use. But as they avoid discharging room air to the outside, there is definitely a savings in conditioning costs for make up air.

    Heat pump dryers are a relatively new option that are often ventless. They are basically fancy dehumidifiers: the hot side of the refrigeration cycle is used to create hot air to blow over the clothes, and then the cold side of the refrigeration cycle is used to condense the moisture out of that air. I expect they are more energy efficient than condensing clothes dryers.

    Cheers, Wayne
